Abstract
In order to enhance the irradiation resistance of erbium-ytterbium co-doped optical fibers for long-range space communication applications, a Radiation-Resistant Erbium-Ytterbium co-doped Fiber (RREYDF) was fabricated by Modified Chemical Vapor Deposition (MCVD). The RREYDFs were irradiated at 300 Gy and 1000 Gy with an average dose rate of 0.2 Gy/s at room temperature using a Co60 irradiation source. The Radiation-Induced Absorption (RIA) at 940 nm and 1550 nm were 0.10 dB/m and 0.22 dB/m at 300 Gy and 0.47 dB/m and 0.36 dB/m at 1000 Gy, respectively. An Erbium-Ytterbium co-doped Fiber Amplifier (EYDFA) with a 1550 nm signal and a 940 nm pump source was built for gain testing. The Radiation-Induced Gain Variation (RIGV) was 0.1 dB (300 Gy) and 1.0 dB (1000 Gy) at a pump power of 7.3 W.
